Tšebeliso ea Lihlahisoa
1.Ascorbic acid, e tsejoang hape e le vithamine C, e sebeletsa mesebetsi e sa tšoaneng ea bohlokoa 'meleng oa motho. E sebetsa e le antioxidant, cofactor bakeng sa liphetoho tse ngata tsa enzymatic, coenzyme, moemeli oa phekolo ea phofo, antioxidant ea lijo, metabolite ea semela, e hloekisa letlalo, le ntho e bolokang mebala ea lijo.
2.Ascorbic acid ke motsoako oa tlhaho oa sehlopha sa unsaturated polyhydroxy alcohols. Ke ketolactone e qhibilihang ka metsing e nang le selikalikoe sa khabone sa litho tse hlano. E na le thepa e matla ea ho fokotsa ka lebaka la litlamo tse peli ho C2 le C3 carbons le lihlopha tse 'nè tsa hydroxyl. Ascorbic acid e sebetsa e le mofani oa hydrogen kapa elektronike, e etsang hore e be cofactor liketsong tse ngata tsa enzymatic.
3. Le hoja liphoofolo tse ngata tse anyesang li ka hlahisa asiti ea ascorbic ka tsoekere, batho ha ba na enzyme e hlokahalang ’me ba tlameha ho e fumana lijong tsa bona. Litlhoko tsa letsatsi le letsatsi tsa ho noa asiti ea ascorbic lia fapana, basali ba hloka hoo e ka bang 75 mg le banna ba ka bang 90 mg. Le hoja litholoana tsa citrus li atisa ho amahanngoa le ascorbic acid, litholoana tse ling, meroho le nama le tsona li sebetsa e le mehloli ea lijo.
4. Ascorbic acid ke ntho e ka sehloohong e nang le boima bo tlase ba molek'hule ea antioxidant e laolang maemo a mefuta ea oksijene e sebetsang (ROS) le ho ntlafatsa katleho ea li-antioxidants tse ling. E bapala karolo ea taolo ea ROS sethaleng sa bona sa sebopeho mme e fana ka tekanyo e le 'ngoe e fokotsang. E susumetsa ts'ebetso ea li-enzyme tsa antioxidant joalo ka superoxide dismutase (SOD) mme e bohlokoa bakeng sa motsoako oa collagen.
Sephutheloana le Polokelo
Sephutheloana:
25kg / moropa oa lebokose kapa joalo ka litlhoko tsa hau.
Tlhokomeliso: Sebopeho le boholo ba lik'hemik'hale li ka ntlafatsoa ho latela litlhoko tsa bareki
Polokelo:
E arotsoe ho li-oxidants tse matla le metheo e matla.Tharollo ea asiti ea ascorbic e kenngoa ka potlako moeeng le mecheng ea alkaline; sethethefatsi se lokela ho sireletsoa moeeng le leseli.
